HABITAT DESCRIPTION: |
|
Found in the higher mountain, usually above 3,000 ft. (Simpson 1992). Breeds in mountainous areas where cliffs or rocky craggs are present for nesting (Hamel 1992, Simpson 1992). Hamel (1992) lists 'open woods, margins, and fields at high elevation,' as well as 'campgounds, picnic areas, dumps, and other places where garbage is left,' as frequent
foraging locations. Nests are often in coniferous trees or on cliff ledges (Harrison 1975, Hamel 1992, Potter et al 1980). Generally it is constructed of sticks, twigs, and thickly lined with moss, wool, hair, grasses, bark shreds (Harrison 1975, Potter et al 1980). The omnivorous raven forages mostly on the ground (Goodwin1976, Hamel 1992, Kaufman 1996,
Potter et al 1980). Large numbers may gather at communal roosts in trees or on cliff ledges (Goodwin1976). NATURE SERVE GLOBAL HABITAT COMMENTS: Various situations from lowlands to mountains, open country to forested regions, and humids regions to desert; most frequently in hilly or mountainous areas, especially in vicinity of cliffs (AOU
1983). Closely associated with humans along Beaufort Sea coast of Alaska (Johnson and Herter 1989). Nests usually on cliff ledges or in coniferous trees, also on man-made structures. See White and Tanner-White (1988) for information on the use of highway overpasses and billboards for nesting in Idaho and Utah. Often reuses nests in successive years.
